Stave-machine



UNITED STATES PATENT OFFICE.

GEORGE STARKWEATHER, OF HARTFORD, CONNECTICUT.

STAVE-MACHINE.

Specification of Letters Patent No. 23,274, dated March 15, 1859.

To all whom it may concern:

Be it known that I, GEORGE STARK- wEA'rI-Inn, of Hartford, county ofI-Iartford, and State of Connecticut, have invented certain new anduseful Improvements in Stave- Dressing Machines; and I do hereby declarethat the same is described and represented in the followingspecification and drawings, and to enable others skilled in the art tomake and use the same I will proceed to describe the construction andoperation, referring tothe drawings, in which the same letters indicatelike parts in each of the figures.

In the accompanying drawings to which this description and letters havereference Figure l is an isometrical view. Fig. 2 is a sectional view.

A, is the frame work.

B, is the shaft, to which the revolving cutter rim C, is secured, by akey or setscrew, and having a driving pulley F, secured on the upper endthereof.

It, is a stop, or box, in which the lower end of the shaft B, issecured, and revolves, and the upper end being secured in the box S.

D, is the outer cutter rim having two flanges T, T.

E, is a pulley rim, rising from the flange T', upon which the belt runs,and drives the cutter rim D, and is supported by and revolves upon thefriction rollers I.

U, V, are fixed or stationary plates, having the necessary openings forthe rollers I, and also for the passage of the staves while beingdressed. The rollers Iproject through the plate V, suflicient so as toallow the cutting rim D to revolve free and clear from the plate V. Thetwo plates U and V, are secured firmly at the desired distance from eachother, as to allow the cutter rim C to revolve free and clear betweenthem by means of the guide bars or bolts lV, which pass through fromplate to plate, between the cutting surfaces of the rim D, C, and placedflush with one side of the feed boxes X, and serves to steady and guidethe stave as it passes downward.

J, are guide rollers fixed in adjustable boxes K, and secured upon theplate Il, and adjusted so as to lit the inside of the pulley rim E, toguide and steady it in place. The cutters G, are made either double orsingle iron, and of such shape as may be desirable, and arranged atsuitable intervals in the rims D, C, and secured thereto by set-screwsH. Underneath the plate V, on the shaft B, is a screw or worm wheel a.,into which gear M meshes, and is secured to the shaft I), and having afeed wheel O, constructed in any of the most desirable forms for thepurpose of feeding the staves gradually through the machine, and innumber to correspond with the number of feed boxes, or apertures, ineach machine for receiving and dressing staves.

Now when the machine is constructed, and set-up for use, the belts areapplied to the vpulleys E and F, and thus giving motion to the revolvingcutting rims D, C, as indicated by the darts. The staves are introducedinto the machine through the feed boxes X, and thus passing throughbetween the cutters Gr, in the rims D, C, and as soon as they passthrough the cutting surface sufficient, they are caught by the feedarrangement and are thus gradually fed through the machine. Thus onestave after the other may be inserted in regular succession, around themachine, and therebydressing several staves at a time. and continuously.This machine may be constructed varying in its mechaniw ca larrangement, without essentially changing the principleof its action.

The advantages derived by this machine over others now in use are theycan be manu factured at much less expense, will dress more rapidly, andboth sides at the same time, and several at a time.

From the foregoing will be seen and understood both the nature of theinvention, and some of the advantages derived by its use over others nowin use.

IVhat I claim therefore and desire to secure by Letters Patent is i l.The horizontal, revolving cutting rims D, C, for dressing staves, on thetwo opposite sides at the same time arranged and operating substantiallyas described.

2. The arrangement of one or more feed boxes X, upon the plate U, overthe cutters G, with the feeder, produced from the worm a, for thepurpose described.
